DESCRIPTION

1-1/2″ x 1-1/2″ x 11 gauge (.120″ wall) square steel tubing is manufactured from ASTM A500 steel, a cold-formed carbon steel specification designed for medium- to heavy-duty structural applications. This hollow structural section (HSS) features a uniform square profile with a thicker wall, offering enhanced strength, rigidity, and durability. Typically produced in Grade B, it provides excellent weldability, precise dimensional consistency, and dependable performance for demanding fabrication and construction projects.

Applications:
1-1/2″ square steel tubing (11ga) is commonly used in:
• Reinforced frames, supports, and brackets
• Medium- to heavy-duty furniture and industrial shelving
• Gates, railings, and security structures
• Equipment enclosures and protective guards
• Automotive fabrication and trailer components
• General industrial and commercial metalwork

Advantages:
• Increased strength: Thicker wall (.120″) supports heavier loads and resists bending
• Durable construction: Suitable for medium- to heavy-duty structural applications
• Excellent weldability: Compatible with MIG, TIG, and stick welding
• Versatile fabrication: Can be cut, drilled, and modified easily
• Consistent quality: Manufactured for uniform dimensions and reliable fit

Summary:
The 1-1/2″ x 1-1/2″ x 11 gauge ASTM A500 square steel tube is a durable and versatile solution for medium- to heavy-duty structural and fabrication projects. Its thicker wall, combined with excellent weldability and strength, makes it ideal for reinforced frames, supports, and load-bearing assemblies.

* Prices subject to change without notice due to the Metals Market fluctuations. | All ‘value length’ and ‘value pack’ item measurements are subject to a “mill tolerance”. | A product may be produced several thousandths of an inch, either over or under the stated thickness, and still be within “mill tolerance”. Since we cut the material specifically for your order, they follow these tolerances: Length: +0.125″ / -0.062” – Please note that during cutting, the blade removes about 1/16″ of material (kerf). This is a normal part of the process and is already considered within the stated tolerances.
